A stethoscope has a dual-sided stethoscope head. The stethoscope head includes a body member having first and second opposite sound collecting sides. Each of the first and second sound collecting sides has a suspended diaphragm member. Preferably, one side is specially adapted for use with adult patients while the other side is specially adapted for use with pediatric or thin patients where it is difficult to obtain good surface contact.
